In this fascinating episode of Resilience Gone Wild, host Jessica Morgenthal speaks with Dr. John Lesku, a leading sleep researcher, about the amazing patterns and processes of sleep in animals of all types —and what they can teach us about human health, resilience, and performance.
From parrotfish building mucus cocoons to sleep safely, to dolphins sleeping in with one eye and half brain alert, to penguins napping in microbursts, and birds sleeping mid-flight, this episode explores the incredible adaptations across species that allow sleep to happen in even the most challenging environments.
Lesku discusses the latest sleep science, including how pollution and urban noise disrupt wildlife sleep, how sleep deprivation impairs cognition in both animals and humans, and why sleep hygiene is vital for long-term wellness. Together, they make a compelling case for rethinking our relationship with rest, emphasizing that sleep is not a luxury—it’s a biological necessity.
Takeaways:
- Sleep is essential to survival and health, both for humans and animals.
- Sleep impacts cognitive function, emotional regulation, and decision-making.
- Sleep deprivation can be as impairing as intoxication.
- Many animals have unique sleep strategies, including unihemispheric sleep in cetaceans, birds and other animals.
- Parrotfish secrete a protective mucus cocoon as a natural sleep defense.
- Penguins and migratory birds thrive with fragmented or polyphasic sleep patterns.
- Urban wildlife adapt sleep to manage noise pollution and artificial light.
- Sensory gating helps humans and more-than-human animals selectively process information while asleep.
- Individual sleep needs vary, and there’s no one-size-fits-all approach.
- Research on animal sleep can inform better human sleep practices and resilience strategies.
